Most heart disease is preventable. Despite that, the typical first encounter with a cardiologist is after a problem has already developed. Cardiovascular risk assessment is a low-cost, low-tech intervention that can change that — provided it actually happens.
Who should be assessed
Australian guidelines recommend a formal cardiovascular risk assessment for:
- All adults aged 45 and over (35 and over for First Nations Australians)
- Adults with diabetes
- Adults with familial hypercholesterolaemia or a strong family history of premature cardiovascular disease
The assessment is usually done at a GP appointment, takes around 20 minutes, and is rebated by Medicare under specific item numbers. It is genuinely worth booking.
What it actually measures
A risk assessment combines several inputs to estimate your absolute five-year risk of a cardiovascular event:
- Age and sex
- Smoking status
- Blood pressure
- Total and HDL cholesterol (a fasting blood test)
- Diabetes status
- Other relevant features (chronic kidney disease, family history, female-specific risk factors)
The output is a percentage risk that places you in low, intermediate, or high categories. The conversation that follows is more important than the number itself: what is driving your risk, and what can be done about it.
What changes the trajectory
A few interventions disproportionately reduce cardiovascular events:
- Stopping smoking
- Treating high blood pressure
- Lowering LDL cholesterol when indicated
- Regular physical activity
- Treating diabetes well
None of these are dramatic. Their value comes from compounding small effects over years.
When to see a cardiologist
Most cardiovascular prevention is well managed by GPs. Specialist review is appropriate when risk is high and not responding to standard therapy, when there are unusual features (premature coronary disease, very high cholesterol, abnormal stress test), or when you and your GP would value a more detailed conversation about prevention strategy.
